Despite slumping revenues and a continuing shortfall for it's FasTracks project, Denver's RTD has secured the right-of-way for a commuter rail line to Boulder. Well, kinda. They didn't secure the rail line into the city proper. In fact, they've gotten as far as Valmont.
To make sure no one is mistaken, this is not the BNSF line from Denver to Boulder, a logical, direct approach which might be accomplished by the Northwest Rail Corridor (pdf). Instead, this is the North Metro Corridor (pdf), the Union Pacific line that follows I-25 to north of the NW Parkway interchange near 162nd Avenue (?!) and then turns west toward Boulder, following a serpentine right-of-way, dodging farms most of the way. RTD has transfer agreements governing the next three sales which will help them build the East Rail Corridor (pdf), the Gold Line (pdf) (Arvada) and a small portion of the West Line (pdf) already underway in Lakewood.
Opinion: Why are we going to Boulder... and, if money is tight, why are we going twice?
